WRIST WATCH Original Filed Dec. 16, 1929 2 Sheets-Sheet? Reiesuecl Aug.24, 1937 UNITED STATES Ohio, assignee 11 Claims.

The present invention relates to wrist watches.

The object of the invention is to provide wrist watches applied moreclosely to the curved surfaces of the wrist and it consists in acombination of aplate and bridges where plate and bridges have their.surfaces facing the casing curvilinear and the surfaces facing thewheels plane, and where owing to a special arrangement of parts the bulkof the watch has been reduced without diminishing the size of partsaccordingly.

In the accompanying drawings one embodiment of the invention has beenillustrated. In the drawings Fig. 1 is a section on the line 1-1 of Fig.2, Fig. 2 is a plan view, Fig. 3 is a side elevation, Figs. 4 and 5 arediagrams showing more clearly by a 'plan and asection the particulararrangement of parts.

According to the Figures 1 to 3 the plate p is provided on its insidesurface with recesses for the different wheels. These recesses are allparallel to each other and perpendicular to the axes of the wheels. Theoutside surface however of the plate is convex so as to fit a casing ofthe same shape. The bridges, 02, 0a which are fixed to the plate arelimited on the side of the wheels by planes parallel to the planes ofthe plate and on the outside by a concave surface fitting that of thecasing not shown. '0; may be curved on the outside also, if necessary.

According to the present invention in the arrangement of parts accordingto the Figs. 4 and 5 the lever escape wheel 11 is not located nearly inthe same plane with the pivoted detent as in ordinary wrist watches, butdirectly above the same, as shown in Fig. 5. This arrangement achievesthe advantages while keeping the rest of 'the movement very lowelevating end n of the casing for locating there the balance wheel I,spring 11, balance cock; is and index fa. Thus 40 the movement utilizesthe space as much as-can be. ment is shortened,'but also the dial hasobtained a solid base, the uniform thickness of the movement has ratherdiminished than increased and the same size of the parts has beenmaintained.

' It will be understood that it is desired to comprehend within theinvention such modifications as may be necessary to adapt it to varyingconditions and uses- What is claimed is:

1. In an oblong wrist watch having a case curved on both sides and allwheeis disposed in parallel planes, 2. plate and bridges positioned onone side of such plate, said plate and said bridges 55 having theirsurfaces facing the case conforming Not only the whole length of themove-' PATENT OFFICE WRIST WATCH k Emile Frey, deceased, late of Bienne,Switzerland, by The Gruen Watch Company,-'Ti1me Hill,
